摘要
采用高真空击密法对某杂货堆场回填形成的黏性填土进行地基处理,通过沉降观测、静力触探、取土试验以及现场载荷试验等进行处理效果的检测.结果表明:处理后的黏性填土地基压缩率为 10%时,地基承载力特征值达到了使用要求;场地内表层的黏性填土的比贯入阻力增长与沉降量呈指数关系;场地内表层的黏性填土的比贯入阻力增长与单位夯击能呈线性关系.研究结果为类似工程提供了较好的借鉴意义.
Abstract
The high vacuum densification method was applied to the foundation treatment of the viscous fill formed by backfill in a general cargo yard,and the treatment effect was tested by settlement observation,static penetration,soil sampling test and field load test.The results showed that when the compressive ratio of the treated viscous fill foundation is 10%,the characteristic value of the bearing capacity of the foundation meet the application requirements.The growth of the specific penetration resistance of the surface layer of the site had an exponential relationship with the settlement,and the growth of the specific penetration resistance of the surface layer of the site had a linear relationship with the unit compaction energy.The research results provided a good reference for the similar projects.
